Fetal Diagnosis of Left Ventricular Aneurysm: A Case Report

Congenital left ventricular aneurysm is a rare but potentially lethal condition. We describe a case of isolated congenital left ventricular aneurysm diagnosed at 28 weeks' gestation. In addition to standard imaging, we utilized color-coded transthoracic tissue Doppler techniques to further evaluate the aneurysm postnatally

A Case of Fetal Diagnosis of Noncompaction Cardiomyopathy and Coarctation of the Aorta

Abstract Background Left ventricular noncompaction (LVNC) cardiomyopathy is a rare form of cardiomyopathy. It is difficult to diagnose prenatally and therefore not well described in the fetal population. There have been a few reports in the literature detailing isolated cases of fetal and neonatal LVNC cardiomyopathy. Case Report We present a case of LVNC cardiomyopathy and coarctation of the aorta detected prenatally at 29 + 6 weeks of gestation with survival in infancy. This is the first case report in the literature describing the fetal diagnosis of noncompaction cardiomyopathy and associated coarctation of the aorta; a rare combination. Conclusion  With a high index of suspicion, the antenatal diagnosis of noncompaction cardiomyopathy may improve neonatal morbidity and mortality

Prenatal Diagnosis and Outcome of Fetuses with Double-Inlet Left Ventricle

The aim of this study is to characterize the in utero presentation of the subtype of double-inlet left ventricle (DILV), a rare congenital heart disease, and assess the postnatal outcome. We retrospectively studied fetuses diagnosed prenatally with DILV between 2007 and 2011. We reviewed the prenatal and postnatal echocardiograms, clinical presentations, karyotypes, and the postnatal outcomes. There were eight fetuses diagnosed with DILV with L-transposition of the great vessels (S, L, L). Mean gestational age at diagnosis was 24.7 weeks. Of these, four fetuses (50%) had pulmonary atresia. One fetus (12.5%) also had tricuspid atresia and coarctation of the aorta and died at 17 months of age. Complete heart block and long QT syndrome was present in one fetus (12.5%), who died shortly after birth. There were no extracardiac or karyotypic abnormalities. Six (75%) infants are alive and doing well. Double-inlet left ventricle with varied presentation can be accurately diagnosed prenatally. The outcome of fetuses is good in the absence of associated rhythm abnormalities with surgically staged procedures leading to a Fontan circulation

“Vanishing” pulmonary valve stenosis

Objective: Both spontaneous resolution and progression of mild pulmonary valve stenosis (PS) have been reported. We reviewed characteristics of the pulmonary valve (PV) to determine factors that could influence resolution of mild PS. Methods: Fifteen asymptomatic pediatric patients with spontaneous resolution of isolated mild PS were retrospectively reviewed. Results: There was no correlation between the PV gradient, clinical presentation, age at diagnosis, or PV morphology. The PV annulus was small at initial presentation, which normalized at follow up. When corrected for the body surface area (z-score), the PV annulus was normal in all patients, including at initial evaluation. Conclusions: Based on our observation, neither age at diagnosis, nor PV-morphology-influenced resolution of mild PS. The variable clinical presentation makes it difficult to categorize and observe mild PS by auscultation alone. The PV annulus z-score could be a useful adjunct to determine the course and serial observation of mild PS
